Hasbro is mashing up Transformers and Scooby-Doo with a two-pack called Mysterious Prime and Automutt, revealed exclusively by IGN. The set hits preorder on July 7 at 10am PT via Hasbro Pulse and other retailers, with a Fall 2026 release window and a $49.99 price tag.
Mysterious Prime is a 6-inch-scale figure that converts from robot mode to the Mystery Machine in 19 steps. In robot mode, collectors can swap between four different heads based on the Mystery Inc. gang — and yes, the figure comes with an ascot accessory, a first for the Transformers line. Automutt, meanwhile, transforms from Scooby-Doo mode to Scooby Snack form in six steps.
This crossover fits into a broader pattern Hasbro has been running with the Transformers brand lately. Recent reveals include a second wave of Transformers x NFL figures, a new Optimus Prime and Megatron set inspired by the 1984 Transformers: The Movie, and the Stranger Things-themed Freakwency and 8-Trax set. Hasbro has clearly found a formula that works — take a beloved Transformer silhouette and rebuild it around an equally recognizable pop culture property.
Preorders open July 7, so fans have a clear date to circle. With Fall 2026 as the target, there's a decent wait ahead, but the ascot alone might be enough to sell this one.
